- 0PGP03-ZX-0002, Condition Reporting Process*
- *
Purpose and Scope
Defines programmatic elements of STPNOC Corrective Action Program (CAP) required to meet regulatory requirements
This procedure DOES NOT govern the handling of Condition Not Adverse to Quality (CNAQ) Condition Reports (CRs). Guidance for CNAQ CRs is contained in 0PGP03-ZX-0008, Condition Not Adverse to Quality (CNAQ) Resolution Process

When should a CR be written?
Condition Reports are written to document an actual or suspected condition that could be a nonconformance, departure from specified requirements, concern, undesirable state, or near miss.
- Conditions with risk to safe operation of the plant or personnel.
- Material deficiencies.
- An abnormal or unexpected condition.
- As required by other station processes or procedures.
- Closed to Trend-Conditions found and corrected (actions taken) that require documentation and trending.

CAQ Significance
Significance Level 1Q (SCAQ) - Condition with major impact warranting investigation. Events or occurrences are expected to happen rarely and consequences are serious.
Significance Level 2Q (CAQ-S) - Condition with moderate impact warranting investigation. Events or occurrences are less serious in nature, examples are defined in this attachment.
Significance Level 3Q (CAQ-D) - Low level Condition could be closed to actions taken, as applicable, such as close to trend. Condition may be non-consequential but actions are required to address issue/behavior.
Significance Level 4 (CNAQ) - Condition with no or minimal impact such as low level material deficiencies on NRS components enhancements, non-consequential issues, tracking issues (e.g. condition not adverse to Quality)

Actions for CR determined to be invalid
Close it!
- Ensure CR description remains unchanged.
- IF Material Deficiency Tag(s) was hung, THEN remove tag and discard in a timely manner.
- Document basis for the invalid determination in the Condition Log Entry field of the CR.

Shift Manager Responsibilities
•Final Operability, Reportability and Functionality determinations.
MAINTAIN and CLOSE the Operability Assessment System (OAS) entry in accordance with 0POP01-ZO-0011, Operability, Functionality, and Reportability Guidance.
•Determining if identified Condition is a Mode restraint.

Which CRs require a Root Cause Analysis ?
High Consequence
Serious degradation of a fission product barrier [e.g. an event meeting the reporting requirements of 10CFR50.72 (b)(3)(ii)]
Exceedance of a safety limit described in the plant technical specifications
Repetitive/recurring conditions associated with a Medium Consequence issue
Any other condition which, if uncorrected, could have a serious effect on nuclear safety

Which CRs may require an Apparent Cause Analysis ?
Medium Consequence
- Licensee Event Report (LER)
- Steam Generator feed pump trip

DESIGNATED QUALIFIED OPERATOR (DQO):
The DQO will only be issued switching orders to open switchyard breakers (owned by the Transmission Service Provider) from the control room.
Unit Supervisors, Shift Managers, and the Unit Operations Managers.

Emergencies:
(reguarding switching orders)
A condition or situation that poses an immediate threat to personnel or equipment, or that impacts system reliability (as determined by CNP transmission Real Time Operations or ERCOT).

OPERATIONAL JURISDICTION:
ALL equipment 345 KV equipment under CNP Operational Jurisdiction. STP only operates Y510, Y520, Y590, Y600 and G19, G20 (transformer disconnects)
The control of when and how equipment is to be operated. One group may have operational jurisdiction while another group actually operates the equipment. Permission must be obtained from the group with operational jurisdiction before any physical operations of equipment may be performed.

- *
TRIP & HOLD:
To trip and physically or mechanically prevent a device from reclosing and hang a Hold Tag on the apparatus.

IF responsibility of a clearance is to be transferred to someone else, THEN
the CNP RTO Controller SHALL accept the release of the clearance from the person leaving and issue a new clearance to the person taking responsibility.
- 0POP01-ZO-0002, 345 kV Switchyard Switching and Clearance Guidelines*
- *
IF communications are broken during switching order instructions, THEN
the DQO SHALL read back all the instructions up to the point of breaking communications before continuing with the switching order.
The DQO taking the switching order from the CNP RTO Controller SHALL write each step of the instructions verbatim on the switching order.

Clearance Release
WHEN work is complete on equipment covered by a clearance, AND the DQO assigned to the clearance has assured himself that all workers and grounds are clear of the equipment, THEN they SHALL contact CNP RTO Controller.
DQO SHALL advise the CNP RTO Controller of the following:
Confirm that maintenance on equipment is complete and request clearance release.
Indicate the number of equipment grounding devices that were removed.
Account for the number of employees who were working on the equipment, other than the DQO.
WHEN all information has been determined to be accurate, THEN the CNP RTO Controller SHALL accept the clearance release.

Purpose and Scope
Establishes the following administrative control programs for managing plant equipment configuration changes:
Operator Aid Program - establishes a mechanism to track information that assists operators in the performance of their duties.
Plant Computer Point Program - establishes a mechanism for tracking Plant Computer points that are removed from scan, removed from alarm checking, or have an entered value.
Plant Computer User Defined Alarm (UDA) Program – establishes a mechanism for tracking Plant Computer Points that have UDA values entered as Compensatory Measures for Material Deficiencies as specified by an approved plant document.
